Specification of Letters Patent.

Application iilcd February 28, 1919. Serial No.'279,759.

. to-obtain a view of objects on either side and in advance of the vehicle body, even if remote and screened by 'intervenlng walls orother obstructions preventing direct vision. v

The principal object of the invention is to provide a plurality of mirrors or reflecting surfaces at the extreme front of the vehicle, so as to project the image of objects at the sides to other-mirrors which are readily seen from within the vehicle,

for instance cars approaching intersecting crossings or entering the street from buildings, etc., thereby materially aiding in avoiding collision and consequent damages.

These and other like objects are attained 'by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which Figure 1 is an illustrative plan view showing a typical street scene and indicating the application of ,the invention.

Fig. 2 is an enlarged plan view showing the arrangement of the mirrors relative to the vehicle and indicating diagrammatically the optical arrangement of the same.

Fig. 3 is a rear view of the same, and

Fig. 4 is a side elevational view showing a modified mounting for the mirrors.

Fig. 5 is a detail sectional view showing a device whichmay be applied to lower the mirrors when desired.

In the view shown in Fig. 1, a conventional type of car, designated by the numeral 10, is indicated aspassing over the level surface of a street 11, the car being close to the sidewalk 12, at the opposite side of which is a building, indicated by the walls 13, partially screened b trees or shrubbery 15, the building being or instance, a gara e containirig other cars 16 and 17, the ast being shown in position to pass out from the door of the garage immediately into the path of the vehicle 10; assuming both cars to be moving, a collision isobviously immi-- neat and to prevent such occurrences is'the mam object of this invention.

'In order to obtain a View from the car 10, prior to its-forward movement, so as to be in the path 'of another vehicle mov-- mg at right angles thereto, as indicated, there is secured to the tubular'filling nozzle 20, of the radiator 21, below the screw cap 22, a split clamp band 23, formed in two equal parts and secured by a bolt 24 at one end, while the other, elongated ends of the band are similarly clamped by a pair of bolts 25, which also pass through a pair of support strips 26, the same being turned at an angle vertically upward, as at 27, and

spread, orming the elements of a fork 28, their outer ends 29 being turned rearward, presenting diverging angular supports to which are secured the backs of the frames 30, containing mirrors or highly polished reflectin surfaces 31, the same being rected dlagonally outward, and adapted to reflect images from other mirrors 32, contained in frames 33, carried by supports 34, the same being angular continuations of bars 35 converging at their inner ends and half between the fork elements 28 by rivets 36.

It is to be understood, however, that the support elements may be fiat metallic bars or strips, tubes or suitable wire rods, and that the mirrors may be round or rectangular as shown, as preferre Thus objects, as indicated by the letter A are reflected from the mirrors 31 to the mirrors 32, and from thence to theeye of the operator taking observations from" a point indicated by the letter B.

In the modification shown in Fig. 4, the I mirror 40 is secured in a holder or frame 41, attached by the hinge elements 42, to a downturned angular support 43 formed with the support bar 44, engaged with the elements 29 or 35, the mirror 40 bein inclinable on the hinge 42, due to an a justing screw 45, threaded into the angularsupport element 43 and movable by a head 46, the point of the screw being engaged in the mirror frame by suitable connections 47, thusproviding means whereby the mirrors may be lncll-ned from a vert1cal reflect the objects in an effective manner.

plane so as to collisions may be forestalled and avoided by reason of any approaching. ob'ects from either side being clearly disclose to the operator of the car, without effort.

Having thus disclosed my invention, in a manner which is to be regarded as descriptive rather than limitative of the device, which obviously may be made in embodiments includin many minor changes without departing from its general scope, .what I claim as new, and desire to secure by Let- .ters Patent is 1. In a device of the class described, a split collar attached to the radiator nozzle of an automobile, a pair of brackets extending horizontally forward from said collar, the ends of said brackets being bent back to- Ward said collar, vertical mirrors on the ends of said brackets, a second pair of horizontal brackets secured between said first named brackets and extending forward therefrom, the ends thereof being bent back toward said collar, and vertical mirrors on the ends of said second-named brackets.

2. Ina device of the class described, a split collar attached to the radiator nozzle of an automobile, a pair of brackets extending horizontall forward from said collar, the ends of sai brackets being bent back toward, said collar, vertical mirrors on the ends of said brackets, a second pair of horizontal brackets secured between said first named brackets. and extending forward therefrom, the ends thereof being bent back towardsaid collar, and vertical mirrors on the ends of said second-named brackets, said first named brackets being pivotally attached to said collar.

3. In a device of the class described, a split collar attached to the radiator nozzle of an automobile, a pair of brackets extending horizontally forward from said collar, the ends of said brackets being bent back toward said collar, vertical mirrors on the ends of said brackets, a second pair of horizontal brackets secured between said first named brackets and extending forward therefrom, the ends thereof being bent back toward said collar, and vertical mirrors on the ends of said second-named brackets, said first named brackets being pivotally attached to said collar, said first named brackets each having a slot formed therein, and said collar having a bayonet slot therein, and a pin adapted to engage in said slots to lock the brackets to the collar.

In testimony whereof I have aflixed my signature this 5th day of February, 1919.
